NAME

6       amzfs-sendrecv - Amanda script to create zfs sendrecv
7

DESCRIPTION

9       amzfs-sendrecv is an Amanda application implementing the Application
10       API. It should not be run by users directly. It create a zfs snapshot
11       of the filesystem and backup the snapshot with 'zfs send'. Snapshot are
12       kept after the backup is done, this increase the disk space use on the
13       client but it is neccesary to be able do to incremental backup. If you
14       want only full backup, you can disable this feature by setting the
15       KEEP-SNAPSHOT property to 'NO'. Only the restoration of the complete
16       backup is allowed, it is impossible to restore a single file.
17
18       The application is run as the amanda user, it must have many zfs
19       priviledge:
20
21           zfs allow -ldu AMANDA_USER mount,create,rename,snapshot,destroy,send,receive FILESYSTEM
22
23       Some system doesn't have "zfs allow", but you can give the Amanda
24       backup user the rights to manipulate ZFS filesystems by using the
25       following command:
26
27       usermod -P "ZFS File System Management,ZFS Storage Management" AMANDA_USER
28       This will require that your run zfs under pfexec, set the PFEXEC
29       property to YES.
30
31       The format of the diskdevice in the disklist (DLE) must be one of:
32
33       Desciption              Example
34       ----------              -------
35       Mountpoint              /data
36       ZFS pool name           datapool
37       ZFS filesystem          datapool/database
38       ZFS logical volume      datapool/dbvol
39
40       The filesystem doesn't need to be mounted.

PROPERTIES

43       This section lists the properties that control amzfs-sendrecv's
44       functionality. See amanda-applications(7) for information on the
45       Application API, application configuration.
46
47       DF-PATH
48
49           Path to the 'df' binary, search in $PATH by default.
50
51       KEEP-SNAPSHOT
52
53           If "YES" (the default), snapshot are kept after the backup, if set
54           to "NO" then snapshot are no kept and incremental backup will fail.
55
56       ZFS-PATH
57
58           Path to the 'zfs' binary, search in $PATH by default.
59
60       PFEXEC-PATH
61
62           Path to the 'pfexec' binary, search in $PATH by default.
63
64       PFEXEC
65
66           If "NO" (the default), pfexec is not used, if set to "YES" then
67           pfexec is used.

EXAMPLE

70       In this example, a dumptype is defined to use amzfs-sendrecv
71       application to backup a zfs filesystem.
72        define application-tool amzfs_sendrecv {
73          comment "amzfs-sendrecv"
74          plugin "amzfs-sendrecv"
75          #property "DF-PATH"  "/usr/sbin/df"
76          #property "KEEP-SNAPSHOT" "YES"
77          #property "ZFS-PATH" "/usr/sbin/zfs"
78          #property "PFEXEC-PATH" "/usr/sbin/pfexec"
79          #property "PFEXEC" "NO"
80        }
81
82        define dumptype user-zfs-sendrecv {
83          program "APPLICATION"
84          application "amzfs_sendrecv"
85        }
