Re: [ADSM-L] incremental backup of many millions of very small files

Been there - done that - went through a complete restore that took days
(could not do NQR for some of it).
Why is journaling "not feasible"?
I have a Windows box with 97M total files (including offsite copy) that
uses journaling and backs up every day. Granted, it takes 7-hours and
uses the minimum memory model (the box is still 2K3 32-bot with 4GB RAM)

Hi,
Can TSM Fastback be a good solution to backup an NTFS filesystem (about
500GB) with tens of millions of files? The daily increment of this
filesystem is about 10-15 GB. Currently we use full daily image backups
with
b/a client. Because incremental (even journaling) is not feasible and
furthermore restore would take even days, I wonder whether the block-level
incremental of FastBack can help in this way?
Thanks so much
