I am not certain if this is the case for Windows Server 2012 R2, but Windows Server Backup in earlier versions was limited to volumes <2TB. This is because the way the software works is to backup to a VHD, and the VHD format is limited to 2TB volumes. I can't seem to find any definitive reference as to whether the 2012R2 version of Windows server Backup ...

You probably need to execute the following command: robocopy /copyall /e /zb However, the lack of versioning is a very serious drawback of such a method. While it is not necessarily wrong, please think twice on your current environment and use it only and only if it really make sense.

Are you really bound by rdiff-backup or you are OK using plain rsync to do incremental backups? Here's a small script that keeps 4 incremental backups. You can change it easily to keep 9 or 99 incremental backups or any other number. It uses the --link-dest option from rsync, creating hard links if files are unchanged. FROM=$HOME TO=/var/backups ...

I use duplicity instead of rdiff-backup but from my understanding your problem is here: My idea was to transfer data initially on physical media to remote server. After that transfer I synchronized the data by rync to make sure they are identical. Now I want to do intial rdiff-backup. Solution that works The simplest solution is to rdiff-backup to ...

For example: ssh www tar c /var/log > /dev/st0 Or use Bacula (or some other full featured backup software), which is very convenient later, but it takes a considerable time to learn. Setting up the client software on a single machine however is less than a minute if it is packaged for your OS.

A NAS is is a fileserver. Period. To reduce shoe-shining, backup systems frequently back up data to a disk pool first, and then when they have enough data accumulated to fill a tape, they'll relocate that backup job to tape all in one session. The disk pool could be a NAS, or it could be a dedicated array of disks connected to a backup server. This is not ...

mftar should according to the docs be able to read straight from the tape so ... mftar < /dev/st0 | tar tvf - If you'd rather grab the data off the tape first and then manipulate with mftar then you can use dd eg dd if=/dev/st0 of=output1 You might need to specify block size with dd. If you don't know how the tape was written then tcopy can give ...

In the scenario you described (failed source drive), rsync will not delete anything, because: by default, rsync does not delete anything until you pass it the "--delete" option even passing it the "--delete" option, rsync will not remove a destination file if the source disk can not be accessed. From the man page: If the sending side detects any I/O ...

You can try using rsnapshot. This uses rsync to create a backup based on hardlinks. On the server, multiple backups can be accessed without wasted space. So when your drive A is erased, only the newest backup will have the data "erased", but the old snapshots will still hold the data. Another thing to do is using the options --backup and --backup-dir ...

Oh, you can set rsync up to not delete extraneous files. By default it doesn't. So if all the files are gone from drive-a, they should be fine. http://unix.stackexchange.com/questions/5451/delete-extraneous-files-from-dest-dir-via-rsync

I wrote an universal script for backup selected databases from MS Sql Server Express. Script loops thru an array of databases and generates separate .bak for every database. Backup filename starts with database name and ends with time and date. Events are logged in log.log file, including database backup task details, so non of existing backups are ...

A common backup software solution used by hosting providers is the Idera CDP suite, which uses the hcp (hot-copy) utility to take point-in-time snapshots without LVM/ZFS/btrFS, etc. The hot-copy tool is available for free. Please also see: CentOS Hot Backup

Linode in particular uses a custom agent in the host OS to back up at a file level. (Linode does some crazy iSCSI stuff that most of us mere mortals will never mess with.) A more widely-used solution is LVM's "snapshot" target (sample write-up here) which is more or less good at hot backups. Basically, if you're using Logical Volume Management, you can tell ...

FreeIPA (now branded as Red Hat Identity Manager on RHEL) as of 4.x includes CLI tools: ipa-backup (producing a GPG-encrypted backup dump of either all server information or LDAP data only) and ipa-restore. One caveat: after restoring a data-only backup on a freshly installed server I found that it clobbered the admin credentials and I couldn't log in as ...

The question is, WHY do you want compression? Compression to improve transfer speed If you want to compress the speed of the transfer, you can add a parameter to rsync to enable on-the-fly compression during the transfer: rsync_short_args -az (source) Compression to reduce space requirements on backup disk rsnapshot seems to real rather badly with ...

You can to do it via ftp instead scp procol. And without encryption. Example with full backup: duplicity full <your-folder-or-file> ftp://user:pass@<host>/backup-folder/ It worked for me. Also I'm trying to do if via sftp or scp but I don't find my issue yet. So is a provisional answer.

If someone had the same problem than me, I solved using duplicity-backup nice and easy to use!

I had similar frustrations, so I ended up creating a few scripts which I'm calling snazzer. Together they offer snapshotting, pruning, measurement and transport via ssh (but as of today can send/receive to/from local filesystems as well). Measurements are just reports of sha512sum and PGP signatures of snapshot paths. It's not quite ready for release but I ...

Short answer yes you can at least with the latest version. I had a similar setup: BackupExec installed on a guest vm for backup all guest VMs on a single host to a nas and a tape. I wasn't enthusiastic about the performance thought. I switched to veeam more straightforward if you have to backup VMs IMHO ( http://www.veeam.com/ )

When you're stuck with using Windows Backup and have no other options, a workaround which I've implemented before is to share the RDX drive and then set Windows Backup to write backups to that share. You're effectively writing your backups to \\localhost\RDX, but it keeps Windows Backup happy if you're happy to put up with Windows Backup's even more limited ...

I strongly suggest to give a look at rsnapshot: it basically is a perl wrapper around rsync with the added benefits of integrated snapshot rotation and much more.

This worked simply by running the task using the administrator credentials. Find that in the Advanced options of your task. :)

No, rsync does not check the access time (atime) of a file. Instead, it use the modified and changed times (ctime/mtime) to check if a file changed. What you should pay attention, however, is that rsync is preserving mtime (-t option) in the fist place. If not, any further attempt will re-sync the same files. rsync -a includes '-rlptgoD' options, so if you ...

The data.mdb file is actually a thin provisioned 86GB (by default) file. Rsync and sometimes cp commands will 'explode' the file to it's full size when copying to a backup directory. This obviously doesn't help if you want to create an offsite backup or if you are limited in resources. This behavior seems new in 8.0.1 The proper way to prevent this is to ...

You can use the cmd_postexec configuration setting to run a custom script after rsnapshot completes. This script can then do anything you want. However, tarring the files after the fact will, if anything, increase the disk usage. Probably by a lot. By default, rsnapshot passes options to rsync such that rsync hardlinks any unchanged files to the previous ...
