* [9fans] advice? fossil+venti (p9), vbackup+venti (p9p) vs. some other means of backup @ 2014-12-11 10:50 Rudolf Sykora 2014-12-11 11:14 ` David du Colombier ` (2 more replies) 0 siblings, 3 replies; 5+ messages in thread From: Rudolf Sykora @ 2014-12-11 10:50 UTC (permalink / raw) To: Fans of the OS Plan 9 from Bell Labs Dear all, I'd like to ask for an advice/experience. Does anybody rely on a backup scheme using, say, vbackup+venti on linux? Does it work well, or would you recomment other means of doing a backup? I guess there are also people using fossil+venti on p9. Are those happy? I am looking for a sustainable means of backup, mainly on linux, and am avaluating different options (rdiff-backup, rsnapshot, dump/restore, rdup...) I have some 500 GB to care about (usual home use + some backup of computational data) Thanks for your comments and sorry for a bit vague question.

Are those happy? I'm using Fossil and Venti on Plan 9 and I'm quite happy. On my typical setup, I've two arenas partitions mirrored on two hard disks using venti/mirrorarenas. My main file server is mirrored to another file server using venti/wrarena every night. I'm regularly dumping arenas to backup hard disks and blu-ray using venti/rdarena. I don't really store any long-term stuff on my Linux machines. I just copy the files to the Plan 9 file servers using v9fs. -- David du Colombier ^ permalink raw reply [flat|nested] 5+ messages in thread

Not precisely what you're asking, but likely close enough experience to be useful: When last I was responsible for a bunch of unix boxes, I was using venti for backup. I started off using vbackup, but switched to something vac-based pretty quickly. I realized there was a ton of data on there that I didn't feel the need to keep backed up (the OS itself, but more significantly nearly a TB of transcoded video (we kept the source backed up)). Also, I don't think I could get at the vbackup images from Plan 9; the vac ones work fine, with some oddities based on file system differences. These were OS X systems, but I was just using stock p9p stuff; it should run fine on linux. I was sending to a remote venti running on Plan 9. Using vac instead of vbackup increases your recovery time (you have to reinstall the OS & tools, and in my case we'd have to re-transcode the video), but we had a warm spare and RAID to guard agains simple disk failures; this was mostly for genuine disaster recovery (although being able to mount and cd around my backup history from my Plan 9 workstation was a huge benefit). I also ran something similar on my laptop. I've stopped using that regularly in favor of Time Machine, but still use it as an occasional one-off for disaster recovery (although it's not off-site). > I guess there are also people using fossil+venti on > p9. Are those happy? Yes, quite. Ever since someone (Richard Miller, I think) tracked down that persistent snapshot hang bug, it's been great. Most of the complaining about fossil's stability comes from outdated info. The fossil+venti combo isn't the fastest option (Erik's kenfs kicks ass there), but the tradeoffs work well for my needs. > I am looking for a sustainable means of backup, > mainly on linux, and am avaluating different options > (rdiff-backup, rsnapshot, dump/restore, rdup...) I would use this system again if I had unix servers I cared about. For my MacBook, Time Machine gets the edge mostly because it's automatic. This is not quite the latest version, but you can take a look at /n/sources/contrib/anothy/bin/rc/vacbak. You can also take a look at .../anothy/lib/tet.(cron files xfiles) for examples of config files I used on a system called tet. You're reminding me I've been meaning to come up with an off-site backup plan for my system, which I haven't had in a few years... ^ permalink raw reply [flat|nested] 5+ messages in thread
