I personally backup my code in S3 using git, using this method: http://www.fancybeans.com/blog/2012/08/24/how-to-use-s3-as-a-private-git-repository/ RDS is already backed-up so I just use the auto-backup feature of RDS for my databases.

For a temporary operation, copying the whole backup dir to another SD host can be easier and quickier than managing duplicates directly in Bareos. The only thing you need to remember to preserve existing backups (both data and catalog) is never change volume names. I would also be careful changing SD instance name (Name = ...), it's safer to only edit the ...

It looks like you're searching for "snapback": https://github.com/markround/XenServer-snapshot-backup . It's a shell script launched by cron on the cluster pool-master and, based on "custom fields" defined on VMs, decide what to backup (xva_backup defined), when to backup (xva_backup=daily|weekly) and how many backup to keep alive (xva_retain). Backups, as ...

I run a large proxmox cluster and have to suggest you change your backup strategy away from the built in vzdump snapshot style backups, which take ages, are always full therefore large in size and make restore of individual files extremely long winded. Consider an 'in guest' file backup solution of which there are many. Backuppc, Urbackup, bacula, amanda ...

Can any one offer any suggestions as to what I should check or what might be wrong here? Just some general recommendations: check the hard drive partitions and ensure they are all NTFS run chkdsk /f /r and make sure there are no bad sectors make sure the clients are not set to go into sleep mode (configure this in Power Options)

There are several possibilities. rsync. It does what you expect it to do, but to do so, it has to read whole file on both ends, compute checksums and transfer the changes. If you are not using rsync remotely (networked filesystem for example), you need to disable whole-file transfer. (--no-whole-file) LVM snapshots + lvmsync as suggested by @womble ...

The only thing you are missing is to quiesce the guest filesystem before taking the snapshot, to ensure that it is consistent. This can be done with virsh domfsfreeze if you are using libvirtd. For example, the order of operations is: # Freeze guest filesystems virsh domfsfreeze $VM_NAME # Create snapshot qemu-img create -f qcow2 -b $VM_NAME.qcow2 ...

I'd recommend using LVM (optionally with thin provisioning) along with lvmsync, but then I'm biased, having written lvmsync for this exact situation. If that doesn't suit, the qemu incremental backup support (as mentioned in a comment by @HBruijn) in newer versions of qemu is available, if you don't mind running bleeding edge code. Unfortunately, the qcow2 ...

Thanks for the responses. Although it is easy to configure the backup server to point to the new NIC of Windows server, how do i ensure that traffic is directed on the dedicated NICs? Ex: Windows 2008 Server Primary NIC - WinSrv1 (172.25.1.10) Secondary NIC - WinSrvBck (172.25.1.50) Backup Server (windows 7) Primary NIC - Srv1 (172.25.1.11) Secondary ...

It's quite simple: add a new network interface to the Win2008 server add a new, dedicated IP address to the new interface configure your Win7 machine to point at the new IP address assigned to the new server interface.

You make sure your backup server can reach the file server via its IP on the separate NIC and then your backup scripts / settings must point to the IP of the new NIC. Easy.

You actually have multiple options, and in the future I hope that you setup some daily / weekly backups of your system. Also, if you hosting provider is unable to clone your dives when they need to replace them in the hardware that you are renting from them, I would suggest you fins a better provider... As mentioned by Sirex, you could use SCP, or even use ...

your lifes work, and you're backing it up only because a drive is failing ? o_O there's very little information to go on here, but generally you'll want scp. http://www.hypexr.org/linux_scp_help.php

It seems that you are running the same job as two different users. The log files should have been able to help you track that down. The timestamps on the dump files confirm multiple users.

They're cheap, but they're not free. You can keep a year's worth of dailies if you want, and if you've got the space, but the moment you start to have disk space pressure, the cost/benefit of keeping them all isn't going to be worth it. Once you're more than a week out, the need for such high fidelity backups tends to disappear.

Create a separate config file for this host cp /etc/rsnapshot.conf /etc/rsnapshot.link.conf Only add the directories where you want the symlinks to be copies and remove all of the other backup definitions. add: rsync_long_args --copy-links near the cmd_rsync /usr/bin/rsync line. and invoke like: rsnapshot -c /etc/rsnapshot.link.conf daily ...

rsyncrypto has been written exactly for this purpose. It allows you to leverage rsync's delta-copy algorithm while encrypting your data locally and storing the encrypted blobs remotely. However, keep in mind that rsyncrypto makes a tradeoff between security and performance.

What you are after is an MD5 checksum. From the Debian Wiki: MD5 Sums are 32 byte character strings that are the result of running the md5sum program against a particular file. Since it is very hard to find two different files that results in same strings, MD5's can be used to determine that the file or iso you downloaded is a bit-for-bit copy of the ...

MySQLDump is not an SQL command. You don't run it from inside MySQL. You run it from the command line. See here.

It seems that, the default "system image" function in Windows 7, does support bitlocker transparently. The backed up image will be unencrypted automatically. Source Alternatively, using third-party software, it's generally recommended to decrypt first before imaging even though it might take some time. This is because imaging a bitlockered drive is usually ...

You are right -- you don't need a third-party secondary in your situation, and it'll offer few improvements to you, provided that all your other services (including the mail) are still hosted on a single box in a single network. Yes, both the primary and secondary are run next to each other; both are supposed to have the same information (but coherence of ...

If you want to backup from Linux to Linux I wouldn’t use dump, because it’s inconvenient when you need to access something inside the backup file. Just using rsync over SSH to do a full system backup should be fine in most cases: rsync -aAXv --delete-after --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} /* ...

You can use vSphere replication to replicate from one host to another. It is not only for cross-vSphere migrations. Veeam's Backup suite can do the same thing with a lot less complexity. So while the built-in vSphere replication product works, recovering from it is a bit of a pain. Veeam is very inexpensive for two hosts, so it's probably worth the ...
