similar to: vfs_shadow_copy2: unmount snapshot while user is restoring from it

Hi Jeremy, The use case is that we want to automatically rotate the snapshots. For example, we want to keep 24 hourly snapshots, and every hour we create a new snapshot and unmount the oldest one. But since customers can be restoring from the oldest snapshot right now, it is not deterministic when we will be able to unmount the oldest snapshot. So at that moment we want all active restore

Hi Uri, Thanks for your response. We do not want to delete the share in smb.conf and later to reconfigure it without the shadow copy. We want to keep the shadow copy and rotate the snapshots. For example, we want to keep 24 hourly snapshots, and every hour we create a new snapshot and unmount the oldest one. But since customers can be restoring from the oldest snapshot right now, it is not

Hi all, Does anyone have vfs_shadow_copy2 working with an alternate snapshot directory format? My snapshots look like this : drwxr-xr-x 55 root root 32768 Jan 10 12:37 20140113_12:00 drwxr-xr-x 55 root root 32768 Jan 10 12:37 20140114_12:00 drwxr-xr-x 55 root root 32768 Jan 10 12:37 20140115_12:00 drwxr-xr-x 55 root root 32768 Jan 10 12:37 20140116_12:00 drwxr-xr-x 55 root root 32768 Jan 10

Hello Dear Samba Users, I have sucessfully set a samba share on a centos 7 box (samba 4.6.2) and succeeded into make work snapshots (vfs_shadow_copy2 with xfs and lvm). The snapshots appears well in windows previous versions. However, I expected to go further with snapshots and use the options "shadow:snapprefix" and "shadow:delimiter"in order to filter daily, weekly

Hi I could not get a custom "shadow:delimiter" for the vfs shadow_copy2 module to work successfully for me with Samba 4.6.2. I did not try previous versions. Based on my testing it seems that an additional line of code is needed in vfs_shadow_copy2.c as shown in the patch below (some comment updates are included too for code readability). Without the below patch, previous versions

Hi all, I'm using the VFS sbadow_copy2 module, and I think I've hit a bug. This config works: mattcen at adam:SambaTest$ cat works3/smb.conf [SambaTest] comment = SambaTest writable = yes path = /srv/SambaTest/share #vfs objects = shadow_copy vfs objects = shadow_copy2 shadow:snapdir = /mnt/dates shadow:basedir = /srv mattcen

Hi, I notice you're using 4.6.2 and I'm using 4.6.11. I made the following comment at some point within [global]:   #disable "unix extensions" to avoid using "allow insecure wide links"   #  for access to ../xxxx_SNAPS for BTRFS "previous versions" snapshots   #  --it seems to have reverted once more to not need the below two settings   ##unix

Hi (+mailing list again for the archives) My config which does show previous versions: # /usr/local/samba/sbin/smbd --version Version 4.6.11 To avoid having this config block within in each share, I define the following within the [global] section:   shadow:snapprefix = ^\(monthly\)\{0,1\}\(weekly\)\{0,1\}\(daily\)\{0,1\}$   shadow:delimiter = _UTC_   shadow:format =

Hello all, I already successfully configured shadow copy service without a delimiter and regex. But as soon as I try to get this to work with regex, nothing shows up on the win client. My config looks like this: [global] shadow: localtime = yes shadow: sort = desc shadow: format = _%FT%T shadow: delimiter = _ shadow: snapprefix = ^\(monthly\)\{0,1\}\(weekly\)\{0,1\}\(daily\)\{0,1\}$

Hi all, At some point recently my customers can no longer see GPFS snapshots under the Windows Previous Versions tab. It simply says "No previous versions available". If a fileset is exported with the flag "force user = root" then Previous Versions *are* displayed. [2016/07/06 10:07:35.602080, 3] ../source3/smbd/vfs.c:1322(check_reduced_name) check_reduced_name:

Hi Sebastian, why are you using shadow:snapprefix if this is just ?snap?? Does it work using ONLY shadow:format = snap_GMT-%Y.%m.%d-%H.%M.%S ? If you use snapprefix you also need to use shadow:delimiter (in your case this would be ?_?). However, I never managed to get it working with snapprefix on my machines.

Hi I am trying to get shadow_copy2 to read gluster snapshots and provide the users with previous versions of their files.

Hi Alexander # net conf delparm projects shadow:snapprefix does not change a thing. The error persists.

Hi, As per the list.samba.org link, did you try including the delimiter within the format, ie as shown in the following? shadow:snapprefix = ^d[A-Za-z0-9]*y$ shadow:delimiter = _IPG_ shadow:format = _IPG_%Y.%m.%d-%H.%M.%S Regards, Mike On 16/02/2018 16:50, Edouard Guigné via samba wrote: > Hello Dear Samba Users, > > I have sucessfully set a samba share on a centos 7 box (samba 4.6.2)
