Hello there, asking for some help with this
I’m using:
Server: UrBackup Server v2.0.31.1544
My client directory contains some symlinks:
[23:52:01] vagrant backup-client01 / $ ll /backup
lrwxrwxrwx 1 vagrant vagrant 11 Jul 27 23:43 dir1 -> dir1.12-34b/
drwxr-xr-x 2 vagrant vagrant 1024 Jul 27 20:55 dir1.12-34b/
drwxr-xr-x 3 vagrant vagrant 1024 Jul 27 20:55 dir2.1-43b/
-rw-r--r-- 1 vagrant vagrant 0 Jul 27 20:55 f1.mkv
-rw-r--r-- 1 vagrant vagrant 0 Jul 27 20:55 f1.mpg
-rw-r--r-- 1 vagrant vagrant 0 Jul 27 20:55 f2.mkv
Backups are working fine, when I check the server backups directory (/backup/urbackup/ in my case), they looks fine:
[23:55:10] root backup-srv ~ $ ll /backup/urbackup/backup-client01/current/backup/
lrwxrwxrwx 1 urbackup urbackup 21 Jul 27 23:43 dir1 -> ../backup/dir1.12-34b/
drwxr-x--- 2 urbackup urbackup 4096 Jul 27 20:55 dir1.12-34b/
drwxr-x--- 3 urbackup urbackup 4096 Jul 27 20:55 dir2.1-43b/
-rwxr-x--- 1 urbackup urbackup 0 Jul 27 20:55 f1.mkv
-rwxr-x--- 1 urbackup urbackup 0 Jul 27 20:55 f1.mpg
-rwxr-x--- 1 urbackup urbackup 0 Jul 27 20:55 f2.mkv
But when I restore current or past backups, the symlinks are restored as empty directories and the owner:group changes to root (please note dir1/ which was a symlink in the original ls)
[23:56:55] root backup-client01 / $ rm -rf /backup/*
[23:57:07] root backup-client01 / $ ls /backup/
[23:57:11] root backup-client01 / $ urbackupclientctl restore-start -b last
Starting restore. Waiting for backup server... |
Restore completed successfully.
[23:57:30] root backup-client01 / $ ll /backup/
drwxr-x--- 2 root root 1024 Jul 27 23:57 dir1/
drwxr-xr-x 2 vagrant vagrant 1024 Jul 27 20:55 dir1.12-34b/
drwxr-xr-x 3 vagrant vagrant 1024 Jul 27 20:55 dir2.1-43b/
-rw-r--r-- 1 vagrant vagrant 0 Jul 27 20:55 f1.mkv
-rw-r--r-- 1 vagrant vagrant 0 Jul 27 20:55 f1.mpg
-rw-r--r-- 1 vagrant vagrant 0 Jul 27 20:55 f2.mkv
This wouldn’t be a problem for regular files, but when backing up applications (like Zimbra which is the one that I’m having problems now) that depends on symlinks, the restore is useless, unless manual intervention (and a lot of scripting) is performed for fixing symlinks/owners.
Any help would be appreciated
Thanks in advance,
PS: My logs are available, but the scenario is easy to reproduce
