More modern versions of ZFS provide a command named zstreamdump which can provide human-readable information from a stream (or image) created using zfs send. This is an example using the commandline: host # zstreamdump < foo.zfs BEGIN record ... toname = zpool/data/foo@04hoursago END checksum = ...

This could be due to shadow copies of your backups. Run this command in elevated cmd to view reserved storage for shadow copies (replace X with your drive letter): vssadmin List ShadowStorage /On=X: To lists all existing shadow copies of a specified volume use: vssadmin List Shadows /For=X: You can delete shadow copies. If /Oldest argument is given, ...

YES, it is possible to do this by getting a list of all of the files in each of the snapshots that duplicity takes (i.e. the first full backup and every incremental) and then compare the file lists and look for the specific file you are concerned with. While it will not show every change to the file unless the file changes less frequently than you make ...

Don't shrink the log file. Leave the log file the size it needs to be and run log backups often enough that it doesn't grow. You can scriptomatically clean up the log backup directory regularly as part of your normal maintenance. This backup script will run automatic cleanup (only keep files for X days). You can also write a script that runs through ...

I use git as a backup for my Windows system, and it's been incredibly useful. At the bottom of the post, I show the scripts I use to configure on a Windows system. Using git as a backup for any system provides 2 big advantages: Unlike commercial solutions often use their own proprietary format, your backup is in an open source format that is widely ...

Thanks to a tip by Wayne Davison, I use the --stats option for backup: rsync -am --stats src/ dest/ Nice little summary at the end, e.g. Number of files: 6765 Number of files transferred: 0 Total file size: 709674 bytes Total transferred file size: 0 bytes (10 more lines)

The passphrase is completely irrelevant if you've lost the master key. Imagine you had a treasure trove locked in a huge safe and you've locked the key to that safe in a locker. The treasure trove is your encfs volume, the key to the locker is your passphrase. The locker is gone now. The key to the locker that has the safe key is of no use when you're trying ...

NetWorker does not do well with symlinks in the saveset. According to p.68 of the 8.1 Administrator's Guide, "If the save set name includes a symbolic link, a save set recovery is not supported." I would recommend switching your saveset name to use the link target name (in your case/TEMPORAL/oracle) to insure you can recover consistently and if you have an ...

Yes, all you need to do is take a snapshot of the disks while the VM is running and copy the backing image while the VM is running off the snapshot. To get rid of the snapshot live, you need to have a fresh version of libvirt and qemu, and you need to either execute virsh blockcommit or virsh blockpull, depending on whether you want the snapshot merged ...

I think you should try with: ssh user@111.11.111.111 tar -c --bzip2 -f - /home/user/example.com/public/ > Backups/File_Backups/example/example_public_`date +%d%b%Y`.tar.bz2

You can only have 9 levels of incrementals, and you will have to start over at level 0. Deleting a level 0 dump will render the dependent incrementals invalid. That said, you can have multiple level 1 dumps. A L1 dump is 'everything since the last L0'. If you have a 1-9 series, a second L1 will contain the cumulative changes in the L2-9 dumps. That second ...

The typical process is to copy the automatic snapshot then launch a separate (usually smaller single-AZ instance) from it. It's not that much of a hassle and it avoids impacting performance of your production instance during the dump too.
