• Critique My Backup and Storage Plan

  - by MetaHyperBolic

  My current storage (RAID-1 off of a hardware RAID card) and backup (a spare drive) solutions for my home network are inadequate. I have too much data scattered on various one-off drives. It is time to evolve. Backups seem simple enough, at least: lots of big drives. However, I am bewildered by the number of choices for small home storage. The Drobo S looks appealing. So does the ReadyNAS. I am not looking for bunches of shiny features, I'm mostly interested in reliability. I am not interested in building Yet Another PC to create a file server or doing something in the cloud, or whatever. I'm stupid, so I am keeping it simple. Requirements for Main Volume: Starting working space roughly 2TB, with options for growth up to 5TB RAID or something RAID-like with at least one parity drive eSATA II for speed during backups Ability to shut down gracefully when alerted of low power by a UPS Optional but Desirable: Will take 2TB drives now with options for the larger 3TB drives coming in 2010-2011 Optional but Desirable: : RAID-6 or something similar, with two parity drives Optional but Desirable: : Hot spare Ethernet connection not required, as the volume will be shared via the same machines which runs my home print server Backups: Backup performed via ROBOCOPY in mirror mode to an external hard drive via a eSATA II connection. Start with rotating between two external 2TB hard drives, will go up to six external 2TB drives. Start with a weekly backup, move to a bi-weekly backup as more drives are added. Move to 3TB drives as the size of my main volume increases. Backup drives will be stored on an off-site location. Hard drives: I plan on buying all of the same model, but different batches from different vendors. I found a "burn-in" utility with which I can pound away on the drives for a couple of weeks before adding them to the backup pool or the main volume. I estimate that I am looking at roughly $1,500 to start, once I start throwing in two TB drives for backup and four for storage. So, are there any obvious flaws in my plan? What have I overlooked? Any suggestions for the storage device for my main volume that fits my requirements? Or do I just keep it simple, 2 drives in RAID-1, then perform due diligence with my backups, accepting that I will have to buy a whole new unit when my data grows past 2TB?

• Backing up Windows Server 2008 R2 to FTP server

  - by Adrian Grigore

  Hi, I'm looking for an inexpensive way of backing up my Windows 2008 R2 dedicated server to an FTP server. To be any useful, the software should also be able to restore the server by using a bootable CD and the backup set stored on the FTP server. So Windows server backup seems to be out of the question. Can anyone recommend any suitable products? Preferably some you have actually tried yourself? Thanks, Adrian Edit: Just to clarify, by inexpensive I mean something that costs 250 EUR or less...

• Back up Windows 2008 SBS to iSCSI disk

  - by Farseeker

  I've almost no experience with SBS 2008, so please excuse my noob question! SBS 2008 only has the most basic backup utility built in as far as I can tell (similar to Vista), and it will only back up to physical volumes. I've read that you can set up a batch task to backup to a network volume, but right now I just need to get something deployed ASAP. We have an iSCSI target with plenty of free space. Is it worth backing up to an iSCSI target? Or am I wasting my time? If I need to do a recovery from the iSCSI disk, how would I go about it?

• Extract duplicity difftar files manually

  - by isnogud

  I have a duplicity backup which i am not able to recover with duplicity. By calling duplicity file:///path/to/backups /path/to/dir, it returns "Local and Remote metadata are syncronized, no sync needed." but the /path/to/dir is empty. I decrypted all backup volumes and I'm able to view and extract the files from the different difftar files. My only problem is that there are files partitioned and saved in folders named after the files. Can anyone give me a simple script or at least a hint how to untar these difftar files so i get the actual files instead of the partitioned ones?

• Backup and Restore ADAM database

  - by kuoson

  Hi, I was trying to backup and restore an ADAM database to a different server the other day. I copied all files under "Program Files/Microsoft ADAM" folder to the same path in the destination server and started the ADAM service in the destination server up. Although the service come back up successfully and I was able to connect to the instance with ADAM ADSI Edit mmc snap-in, I found I had to reset every single user's password before they can login again. Has anyone got this issue before? Is the password encrypted with the server IP address or something like that?

• Difficulty restoring a differential backup in SQL Server, 2 media families are expected or no files are ready for rollforward

  - by digiguru

  I have sql backups copied from server A to server B on a nightly basis. We want to move the sql server from server A to server B without much downtime, but the files are very large. I assumed that performing a differential backup and restore would solve the problem with the databases. Copy full backup from server A to copy to server B (10+gb) Open SQL Server Managment Studio on server B Right mouse on databases Restore Database Type in the new DB-name Choose "From Device" and browse to the backup file Click Okay. This is now resorting the original "full" backup. Test new db with dev application - everything works :) On original database rightmouse on DB Tasks Backup... Backup Type = Differential, Backup to disk, add a new file, and remove the old one (it needs to be a small file to transfer for the smallest amount of outage) Copy the diff backup onto the new db Right mouse on DB Tasks Restore Database This is where I get stuck. If I add both the new differential file, and the original backup to the restore process I get an error The media loaded on "M:\path\to\backup\full.bak" is formatted to support 1 media families, but 2 media families are expected according to the backup device specification. RESTORE HEADERONLY is terminating abnormally. But if I try to restore using just the differential file I get System.Data.SqlClient.SqlError: The log or differential backup cannot be restored because no files are ready to rollforward. (Microsoft.SqlServer.Smo) Any idea how to do it? Is there a better way of restoring backups with limited downtime?

• How do I create a read only MySQL user for backup purposes with mysqldump?

  - by stickmangumby

  I'm using the automysqlbackup script to dump my mysql databases, but I want to have a read-only user to do this with so that I'm not storing my root database password in a plaintext file. I've created a user like so: grant select, lock tables on *.* to 'username'@'localhost' identified by 'password'; When I run mysqldump (either through automysqlbackup or directly) I get the following warning: mysqldump: Got error: 1044: Access denied for user 'username'@'localhost' to database 'information_schema' when using LOCK TABLES Am I doing it wrong? Do I need additional grants for my readonly user? Or can only root lock the information_schema table? What's going on? Edit: GAH and now it works. I may not have run FLUSH PRIVILEGES previously. As an aside, how often does this occur automatically? Edit: No, it doesn't work. Running mysqldump -u username -p --all-databases > dump.sql manually doesn't generate an error, but doesn't dump information_schema. automysqlbackup does raise an error.

• Backup / Disaster Recovery, should I store RAR-compressed files?

  - by moraleida

  I'm in the process of recovering files from an accidentally formated Ext4 partition using Photorec. It had about 300Gb of data, of which I've already got hold of about 30Gb. So far, it seems to me that the recovery of RAR-compressed files has been much more successful than the recovery of individual uncompressed files and ZIP compressed files - in the sense that a lot of recovered files/zips were unreadable, and pretty much all of the RAR files were intact. Is there such a relation? Are RAR-compressed files really less prone to corruption and thus easier to recover?

• Time Machine for Windows

  - by Kevin L.

  A simple Google search for "Time Machine for Windows" results in a flurry of different little apps. But instead of relying on forum anecdotes and advertisements, I call on the much wiser Super User beta community for some depth on this one. Having Time Machine running on Leopard is like a warm, fuzzy blanket of comfort that I never got with RAID, rsync, or SyncToy on Windows. I'm not asking the community what the "best" backup software for Windows is, but instead: Is there any true Time Machine clone for Windows, one that includes as many of the following as possible: Completely transparent, "set-it-and-forget-it" backup Incremental backups (changes only) for every hour for a day, every day for a month, and every week until the backup disk is full Ability to rebuild from this backup disk in case of main drive meltdown (the backup doesn't have to be bootable; neither are Time Machine disks) Extremely easy to use UI (target user == wife). Bonus points for a beautiful UI

• Why does this rsnapshot exclude not work?

  - by bstpierre

  Rsnapshot passes excludes directly to rsync, but rsync's behavior appears inconsistent. I've simplified my rsnapshot backup test to the following directory tree (this tree will be backed up): gorilla:~# find /tmp/snaptest -exec file {} \; /tmp/snaptest: directory /tmp/snaptest/SKIPTHIS: directory /tmp/snaptest/SKIPTHIS/xyz: directory /tmp/snaptest/SKIPTHIS/xyz/testing: ASCII text /tmp/snaptest/SKIPTHIS/bar: ASCII text /tmp/snaptest/SKIPTHIS/foo: ASCII text /tmp/snaptest/SKIPTHIS.txt: ASCII text My config file: config_version 1.2 snapshot_root /tmp/backup-media no_create_root 1 cmd_cp /bin/cp cmd_rm /bin/rm cmd_rsync /usr/bin/rsync cmd_ssh /usr/bin/ssh cmd_logger /usr/bin/logger cmd_du /usr/bin/du interval hourly 6 interval daily 7 interval weekly 4 interval monthly 3 verbose 3 loglevel 3 logfile /media/maxtor-one-touch/rsnapshot.log lockfile /media/maxtor-one-touch/backups/.rsnapshot.pid rsync_short_args -a rsync_long_args --delete --numeric-ids --relative --delete-excluded exclude "SKIPTHIS/**" link_dest 1 backup /tmp/snaptest snaptest The result: gorilla:~# rsnapshot -c /tmp/snaptest.conf hourly echo 12638 > /media/maxtor-one-touch/backups/.rsnapshot.pid mkdir -m 0755 -p /tmp/backup-media/hourly.0/ /usr/bin/rsync -a --delete --numeric-ids --relative --delete-excluded \ --exclude="SKIPTHIS/**" /tmp/snaptest \ /tmp/backup-media/hourly.0/snaptest touch /tmp/backup-media/hourly.0/ rm -f /media/maxtor-one-touch/backups/.rsnapshot.pid gorilla:~# find /tmp/backup-media/ -exec file {} \; /tmp/backup-media/: directory /tmp/backup-media/hourly.0: directory /tmp/backup-media/hourly.0/snaptest: directory /tmp/backup-media/hourly.0/snaptest/tmp: sticky directory /tmp/backup-media/hourly.0/snaptest/tmp/snaptest: directory /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS: directory /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS/xyz: directory /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS/xyz/testing: ASCII text /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS/bar: ASCII text /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS/foo: ASCII text /tmp/backup-media/hourly.0/snaptest/tmp/snaptest/SKIPTHIS.txt: ASCII text My confusion stems from the fact that if I copy-paste the rsync command echoed by rsnapshot, the SKIPTHIS directory is excluded! (I've tested with various other SKIPTHIS patterns with the same results.) Any idea what's going on?

• Amazon EC2 EBS volume scheduled backup/snapshots using puppet

  - by Ehrann Mehdan

  I am not a Linux admin, although I wish I was, and I have seen these questions Amazon EC2 Backup Strategy Amazon EC2 + EBS:: Regular backup plan? Simple Backup Strategy for Amazon EC2 instances / volumes? And this suggestion http://alestic.com/2009/09/ec2-consistent-snapshot I tried using command line + crontab (the command line works, but crontab for some reason, doesn't) But I'm still pretty lost, all I want is an automated, rolling backup of my amazon EC2 (EBS) data (by rolling I mean keep 3-4 weeks back, but delete old snapshots as new ones come for cost control) And as things usually go, if there is something that is hard and painful, someone creates a solution for it. My question is simple, is there a way using a tool like Puppet to do it without a painful learning curve? (or via other tools like http://ylastic.com) If yes, how?

• Free solution to backup folders to external SFTP server with shadow copy

  - by Sergiy Byelozyorov

  I have an account in university on Linux machine with 10TB of free space accessible via SFTP. I would like to backup my Windows 7 x64 laptop to university. Currently I am using rsync+cygwin, but backup is pretty slow (without shadow copy) and I hate console window appearing every day on my screen when I login. So I am looking for something like Windows Backup but with support for SFTP. Combination of tools will work too.

• Backup IMAP mail, then access via IMAP again

  - by pauldoo

  I am looking for a tool to backup an entire IMAP account and then expose that backup (read-only) via IMAP again. This would be perfect for backing up email from any provider, and allowing the backup to be accessed from any mail client even years after closing the account. I suspect this could be achieved using a full blown IMAP server by configuring it to mirror some other server; but I am hoping for a simpler solution.

• How do I improve my incremental-backup performance?

  - by Alistair Bell

  I'm currently using the traditional rsync+cp -al method to create incremental/snapshot backups of our server tree. The backups are going onto a pair of eight-disk towers connected to the backup machine (a Sandy Bridge machine with 16 GB of RAM, running CentOS 5.5) via four eSATA connections (four disks per connection). Each disk is a regular 2 TB disk, so we have 32 TB of disk space connected to the backup machine. We're backing up about 20 TB of data on the servers with this. The problem is that each daily backup is taking more than 24 hours, and the real time-killer isn't the actual rsync, but the time it takes to perform a cp -al of the tree locally on the backup machine. It's taking more than 12 hours just to make the shadow copy of the tree, and as far as I can tell the performance backlog is at the disk (top shows the cp using a lot of RAM but not a lot of CPU and mostly in uninterruptible-sleep state) We have the server data split into four major volumes (and a few minor ones), and each of these backups runs in parallel (with some offsets in the cron to try to get some disks' cp done first). There are two volumes on the backup drive, both striped LVM volumes of 16 TB each. So obviously I need to improve the performance because it's unusable as it stands. The first question is: when CentOS 6 comes out, with support for btrfs, will making snapshots of subvolumes with btrfs substantially increase this performance? The second is: is there a way, with ext3 or something else supported in CentOS 5 or 6, to 'encourage' it to put the directories/inodes in one part of a volume (which could happen to be the part that's on an SSD, via LVM) and the files in another? That would presumably solve the problem, but I don't know of ways to hint ext3 like that.

• Backup to Synology NAS using rsync or NFS and hardlinks

  - by danilo

  I want to backup data from a Windows (Vista) computer to a Synology NAS (210j). The NAS supports FTP, SMB, NFS and also allows a rsync daemon to be set up. I want to backup different folders to the NAS, but I'd prefer to use the hardlink method to save diskspace (like this script does). With this method, a new folder is created for every backup, but if the file already exists on the target, only a hardlink is created. The filesystem on the Synology device is ext3, so I probably can't use rsyncbackup, as it is made for NTFS. Is there another way to do this backup with hardlink support?

• Virtualizor + VPS Backup (Bare Metal Restore capable) Using rSync 3

  - by Gaia

  I am using virtualizor to manage 3 XEN VPS. Hardware node and each VPS run CentOS 5.x. My backup needs are as follows: 1) I need to be able to bare metal restore the entire hardware node, excluding the VPSes (which would be restored via #2 below) 2) I need to have a complete backup of each VPS, ideally a backup that can be deployed on any other host that uses Xen, if the need arises. Naturally, I would also need to use this backup to restore an entire VPS to an earlier state within the same host. Which folders rSync needs to keep backed up in order to accomplish the above? The rSync specialists aren't sure of it either. Thanks
