Re: Backup systems?
I've use NetApps and now use ZFS. Both have snapshots. Both can be setup (NetApp is by default) to take a snapshot every X minutes, hour, day, week month. They typically add about 10% to the space and really help with the oops I deleted things. I want something for when 2 drives die and also to archive a point in time onto tape/DVD to store offsite. I don't trust an unpowered external drive to preserve the data; the manufactures don't design or test for that. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Re: Backup systems?
I've been using backup-pc with good results. I started making my own rsync scripts and decided that I had better things to do and backup-pc had already done a better job than I ever would.

It also preserves hard-links. This is handy for dealing with files where deltas are not very useful. I backup those (non-delta) files - typically web sites where lots of files are replaced - with dirvish. I believe that's now a dead project, but has been working for me. dirvish creates date named directories (e.g. 2010-10-19) with unchanged files hard-linked across the proper range of date directories. (I assume rsnapshot uses a similar hard-link approach.) I use rdiff-backup to handle the dirvish directories and everything else. rdiff-backup is not locked into a daily schedule like dirvish, but simply creates new deltas each time it runs. So long as you want the most recent version of a file, you can simply copy it out of the backup directory tree. Restoring to a point in the past requires using the rdiff-backup command-line interface to specify the desired point in time for restoration. Then use tapes or external drives to capture the rdiff-backup directory tree and store them off-site. There is no incremental tape backup. You have the full history on every tape. You can efficiently layer rdiff-backup over rsnapshot, but probably not the reverse. -- Lloyd Kvam Venix Corp DLSLUG/GNHLUG library http://dlslug.org/library.html http://www.librarything.com/catalog/dlslug http://www.librarything.com/catalog/dlslugsort=stamp http://www.librarything.com/rss/recent/dlslug ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
