Rollback or increments could be necessary if someone deletes email prior to the last backup and it is later discovered by (that person's boss) well after the fact (and the last backup). I had been keeping about 1 month back in "delta files" necessary to re-create previous backup data.
Though I later realized that seldom does the contents of one file/message change in a mail server, so just having a file-level increment (instead of bit/block-level) is necessary under the right circumstances. -Pat Ring -----Original Message----- From: Eric Shubert [mailto:e...@shubes.net] Sent: Tuesday, March 29, 2011 12:55 PM To: qmailtoaster-list@qmailtoaster.com Subject: [qmailtoaster] Re: qtp-backup I think you can do incrementals with rsync as well. I haven't implemented this yet, but I hope to in the near future. I can't think of why rollback would be wanted or needed with QMT, at least where messages are concerned. -- -Eric 'shubes' On 03/29/2011 10:25 AM, Patrick Ring wrote: > I had played with a similar rsync method to this for a while as well > as adapting a rdiff-backup method as well (allows for > snapshot/rollback/increments). > > I think the rsync is the way to go if you don't need rollback > increments. > It will cut down on bandwidth and time. > -Pat Ring > > -----Original Message----- > From: Eric Shubert [mailto:e...@shubes.net] > Sent: Tuesday, March 29, 2011 12:07 PM > To: qmailtoaster-list@qmailtoaster.com > Subject: [qmailtoaster] Re: qtp-backup > > I using rsync to back up the /home/vpopmail/domains directory.
