similar to: Rsync and differential Backups

Folks I have been using rsnapshot for years now. The only problem I've found is that it is possible to run out of inodes. So my heads-up is that when you create the file system, ensure you have more than the default inodes - I usually multiply the default by 10. Otherwise you can find your 1Tb USB drive failing after 259Mb and you can't then recover the files. Rather embarrassing. >

I guess that makes sense, but in backup systems based on rsync and hard links (such as rsnapshot), *every*

Hi, As all ours *nix systems: ? rsnapshot ?. It?s very simple, based on rsync and assume historical backup on a real Unix FS. So, restauration is as simple then backup. > Le 27 janv. 2019 ? 12:56, Alessandro Baggi <alessandro.baggi at gmail.com> a ?crit : > > Hey there, > what type of backup solution do you use on C7? > > > Thanks in advance >

Once rsync has passed through a given section of the tree, it will not see any subsequent changes. I think you miss my meaning. Consider this sequence of events: * "find" begins and processes dirA and then dirB * another application writes

I'm using Rsnapshot on all my CentOS 7 servers. It's a very elegant solution that follows the KISS principle. I've written a little blog article

Hi list, how to perform a differential backup using rsync? On web there is a great confusion about diff backup concept when searched with rsync. Users says diff because it copy only differences. For me differential is backup from last full backup. Other users says that to perform a differential backup I must include in rsync command: --backup --backup-dir=/some/path but from manual page of

XFS handles this fine. I have a backuppc storage pool with backups of 27 servers going back a year... now, I just have 30 days of incrementals, and 12 months of fulls, but in backuppc's

Will this be very slow if Alessandro has a large number of files? OTOH if he really needs to ensure integrity there likely isn't a better option. --keith -- kkeller at
